One of the most surprising moments of my talk at QCon San Francisco last week was when I asked the audience who is ‘doing’ service oriented architecture inside their Enterprise.
Everyone raised their hand, or nearly everyone. There was no hesitation. The question was clear and the response was swift. Attendees didn’t look around to see if they were the only one riding this ‘dead’ trend. Instinct took over and hands shot up all around. The same question last year at the same conference yielded a positive response from less than half the respondents. Sure, this experiment is anecdotal with a mere slice of the relevant respondents and absolutely no control group, but I think it validates Gartner’s plateau of productivity for services. Productive yes, but maximally productive – no. For internal services to be realized more fully, SOA needs API management.
API Sharing – What’s That?
I talked to attendee after attendee, all with a similar story. The story was how their Enterprise decomposed their assets into programmable services using SOA and hosted their services on vendor platforms (IBM,Tibco, Microsoft) and/or open source. An informal survey yielded most developers using Spring, Jersey or Ruby on Rails as popular ways to host internal services. While services were plentiful, there was simply no single pane of glass, or single source of the truth for internal developers to go to discover and make use of disparate services.
APIs, which in one sense are the closest thing to any developer’s heart, were also the most elusive. For the day to day practitioner, the developer, there is still a significant mental gap between SOAP web services and “APIs.” Many attendees hadn’t heard of solutions for internal SOA governance of the registry/repository ilk and the distance between SOAP and API management seems like light-years. Public and open API programs didn’t seem to “apply” to the quandary of the day to day developer.
Even when valuable functionality is implemented, I heard horror stories of services being implemented twice or three times over in different parts of the Enterprise simply because developers didn’t know that this functionality already existed and had no good way to reuse the components. A service hiding behind a WSDL on Microsoft .NET with zero discoverability is like an invisibility cloak on your SOA. The functionality is there, but almost impossible to use unless you are the original developer or an asetic monk that regularly engages in <wsdl:definitions> tag torture.
It’s time for an API Management invasion. API management has optimized the process for developer on-boarding and fast time to market for services. Developer portals shine in solving this problem. Why? Because they’ve been battle-tested on the open Internet, with hundreds or thousands of “zero-trust” developers. The model is there, it just needs a way to invade the Enterprise. If you are like any of the attendees I talked to last week and already have a SOA that isn’t delivering value, consider how you might apply best practices such as an internal developer portal, fast on-boarding processes, interactive documentation, analytics and other best practices from the open API movement to evangelize and share your components from within. Invade your SOA with API Management.
"We build IoT infrastructure products - when you have to integrate different devices, different systems and cloud you have to build an application to do that but we eliminate the need to build an application. Our products can integrate any device, any system, any cloud regardless of protocol," explained Peter Jung, Chief Product Officer at Pulzze Systems, in this SYS-CON.tv interview at @ThingsExpo, held November 1-3, 2016, at the Santa Clara Convention Center in Santa Clara, CA.

When it comes to cloud computing, the ability to turn massive amounts of compute cores on and off on demand sounds attractive to IT staff, who need to manage peaks and valleys in user activity. With cloud bursting, the majority of the data can stay on premises while tapping into compute from public cloud providers, reducing risk and minimizing need to move large files. In his session at 18th Cloud Expo, Scott Jeschonek, Director of Product Management at Avere Systems, discussed the IT and busin...

Between 2005 and 2020, data volumes will grow by a factor of 300 – enough data to stack CDs from the earth to the moon 162 times. This has come to be known as the ‘big data’ phenomenon. Unfortunately, traditional approaches to handling, storing and analyzing data aren’t adequate at this scale: they’re too costly, slow and physically cumbersome to keep up. Fortunately, in response a new breed of technology has emerged that is cheaper, faster and more scalable. Yet, in meeting these new needs they...

The cloud promises new levels of agility and cost-savings for Big Data, data warehousing and analytics. But it’s challenging to understand all the options – from IaaS and PaaS to newer services like HaaS (Hadoop as a Service) and BDaaS (Big Data as a Service). In her session at @BigDataExpo at @ThingsExpo, Hannah Smalltree, a director at Cazena, provided an educational overview of emerging “as-a-service” options for Big Data in the cloud. This is critical background for IT and data professionals...

"Once customers get a year into their IoT deployments, they start to realize that they may have been shortsighted in the ways they built out their deployment and the key thing I see a lot of people looking at is - how can I take equipment data, pull it back in an IoT solution and show it in a dashboard," stated Dave McCarthy, Director of Products at Bsquare Corporation, in this SYS-CON.tv interview at @ThingsExpo, held November 1-3, 2016, at the Santa Clara Convention Center in Santa Clara, CA.

Fact is, enterprises have significant legacy voice infrastructure that’s costly to replace with pure IP solutions. How can we bring this analog infrastructure into our shiny new cloud applications? There are proven methods to bind both legacy voice applications and traditional PSTN audio into cloud-based applications and services at a carrier scale. Some of the most successful implementations leverage WebRTC, WebSockets, SIP and other open source technologies. In his session at @ThingsExpo, Da...

In his session at 19th Cloud Expo, Claude Remillard, Principal Program Manager in Developer Division at Microsoft, contrasted how his team used config as code and immutable patterns for continuous delivery of microservices and apps to the cloud. He showed how the immutable patterns helps developers do away with most of the complexity of config as code-enabling scenarios such as rollback, zero downtime upgrades with far greater simplicity. He also demoed building immutable pipelines in the cloud ...

Today we can collect lots and lots of performance data. We build beautiful dashboards and even have fancy query languages to access and transform the data. Still performance data is a secret language only a couple of people understand. The more business becomes digital the more stakeholders are interested in this data including how it relates to business. Some of these people have never used a monitoring tool before. They have a question on their mind like “How is my application doing” but no id...

In IT, we sometimes coin terms for things before we know exactly what they are and how they’ll be used. The resulting terms may capture a common set of aspirations and goals – as “cloud” did broadly for on-demand, self-service, and flexible computing. But such a term can also lump together diverse and even competing practices, technologies, and priorities to the point where important distinctions are glossed over and lost.

Predictive analytics tools monitor, report, and troubleshoot in order to make proactive decisions about the health, performance, and utilization of storage. Most enterprises combine cloud and on-premise storage, resulting in blended environments of physical, virtual, cloud, and other platforms, which justifies more sophisticated storage analytics. In his session at 18th Cloud Expo, Peter McCallum, Vice President of Datacenter Solutions at FalconStor, discussed using predictive analytics to mon...
